Vihart: Peace for Triple Piano. (YouTube 3D video, 4:15min)
This has got to be one of the most amazing things done with a 3D camera I’ve ever seen. Pro tip: Watch this in fullscreen mode on your phone so you can look around by moving the entire phone, and use headphones to get the full 3D sound effect as well.

Henry Segerman: The Making of “Peace for Triple Piano”. (YouTube video, 13:52min including a “flat” version of the above 3D video).
In this video Vi Hart and Henry Sergerman explain how the video works: how they made one grand piano and one Vi look like three, but one Henry look like only two at the same time.
Vi writes a little more about this project on her weblog: Vihart.com: Peace for Triple Piano.

XKCD What if: Earth-Moon Fire Pole. “My son (5y) asked me today: If there were a kind of a fireman’s pole from the Moon down to the Earth, how long would it take to slide all the way from the Moon to the Earth? – Ramon Schönborn, Germany”
I loved this and am tempted to use it in one of my next physics lessons…

The Washington Post: Gun violence’s distant echo. “After school shootings, a teenager challenges the gun culture in her conservative Wyoming town.”
“Alan had rarely heard anything described as liberal in northeast Wyoming, and now he listened as the disc jockey explained how 10 Campbell County High School students had marched downtown the previous afternoon to demand tighter gun laws. They said they wanted mandatory background checks on all gun purchases. They said they wanted to build a gun-control movement in solidarity with survivors of a shooting in Parkland, Fla., and tens of thousands of other teenagers protesting across the country.
“They should be expelled,” Alan remembered joking to his co-worker, once the radio switched back to classic rock and they turned onto the highway toward Gillette. “That bleeding-heart nonsense might fly in New York or D.C., but in Wyoming? That’s treason.”
He parked at a ramshackle house on the outskirts of town, where the newspaper waited at the kitchen table. On the front page he noticed a story about the gun protest, the first that anyone could remember in Gillette. “A Walkout for Change,” the headline read. Above that was a picture of several students marching, and there in the midst of them, holding a protest sign, was his 16-year-old daughter, Moriah.”

A music video that was shot in just four seconds and then slowed down to fit over four minutes of music. Here’s how they did it:

Deutsche Welle: Gewalt gegen Lehrer an jeder dritten Grundschule. “An etwa jeder dritten Grundschule in Deutschland sind Lehrerinnen und Lehrer binnen fünf Jahren laut einer neuen Studie körperlich angegriffen worden. Dies berichten die Schulleitungen in einer Umfrage.”
“Der VBE verlangt von den Kultusministerien, die Lehrer stärker zu unterstützen und Statistiken zur Gewalt an Schulen zu führen. Beckmann erhebt schwere Vorwürfe gegen die Landesministerien und hält vor allem eine unbürokratische Meldung und schnelle Hilfe nach einem Vorfall für entscheidend. “Außerdem sehen wir einen klaren Zusammenhang zwischen dem Ressourcenmangel an den Schulen, dem Bild von der Schule als Reparaturbetrieb der Gesellschaft und damit verbunden enttäuschten Erwartungen von allen Seiten”, erklärte der Verbandsvorsitzende.”
